IMPROVEMENT IN STATION-INDICATORS.

Specification forming part of Letters Patent No. 156,607, dated November3, 1874 application led September 23, 1874.

To all whom it may concern:

Be it known that I, PORTER W. TAYLOR, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Advertising-Indicator; and I do hereby declare the following` tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which for'n partof this specification, in Which- Figure l is a vertical section. Fig. 2is a front view. Fig. 3 is a detailed sectional view. i

My invention has for its object to provide an improved street andstation indicator especially adapted to the display of advertisements.

My invention consists in the peculiar and novel construction of parts,having reference particularly to the band on which the names of thestreets or stations and advertisements are delineated.

Referring to the accompanying drawing, A represents the exterior box orframe of the device, having windows a a', through which the names of thestreets or stations and advertisements are respectively observed. Bshows an internal metallic frame fastened securely at the rear to thepiece A', representing the side of the car." C represents a shaftmounted in the sides of the frame B, having a ratchet, G1, spur-wheelG2, and ratchet C3. The ratchet C1 and ratchet C3, the latter shown indotted lines, are fast upon the shaftG,while the wheel C2 is loose uponsaid shaft. D is a lever fast upon the shaft C. o is a dog piv-V oted onthe spur-wheel C2, and c1 is a springpawl engaging with ratchet G3. Whenthe lower end of the lever D is raised by pulling upon the cord d ashoulder, c2, of the ratchet C1 engages with the dog c, causing thespurwheel U2 to be moved, giving motion to the pinion E and revolvingband F. The band F, which starts from the pinionshaft I, passes insuccession over the roller-shafts PI and G, terlninatin g on the shaftl. From the said shaft I starts the band K, (which may be separate fromthe band F or merely a continuation of the 1atter,) passing successivelyover the rollershafts L, M, N, and O, and winding upon the shaft P. Theband F is designed to display the name of the street o r station, whilethe band K is intended for the reception of advertisements. When the`cord d is pulled, actuating the wheel G2, the band F will move down,bringing the name of the next street or station into view at the upperWindow a, while the band K will moveupward, showing a new advertisementat the lower window a.

The advantage of this peculiar arrangement over that heretofore adopted,wherein the advertisements and names of streets or stations alternatedon a single band, the former occupying the spaces between the latter, isthat a movement of the band one-half the distance heretofore requiredwill be sufficient to produce a change of street or station name andchange of advertisements. In other words, when the advertisement andstreet or station names succeeded alternately on the band, the names ofthe streets occupied distances widely apart, and hence a considerablemotion of the band was necessary to change from one street-name toanother. By the present arrangement, however, the street-names followone another in close succession on the band, and hence a slight throw ofthe lever will effect a change of the name displayed. Thepinion-shafteissustained in a pivoted frame, R, swinging on the shaft Q, said shaft egearing with the shaft P. by means Of the gear-wheels e p, Fig. 3. Thegravity of this frame will cause the pinion e to drop out of gear withthe spur-wheel C2 Whenever the dog Sis turned back, as shown in dottedlines, which may be done by means of an external handle or button. Thepinion is thus thrown out of gear whenever it is desired to rewind thebands F and K upon the shaft I, which it is necessary to do at the endof the route, by which time vboth bands will have been wound upon theshafts E and P respectively. The winding is effected by applying a keyto the squared end of the shaft I, which is made to project beyondthe'case A for that purpose. Connected with the lever D is a pi votedarm,

T, by which, whenever said lever is raised, a

gong will be struckand an alarm sounded, thus calling attention to thechange of name and advertisement.

What I claim as my invention is- 1. The combination, with the band orbands ing the pinionshaft E and shaft P geared F K Winding from theroller I upon the rollers therewith, in combination with a station-indi-E P, of the rollers H G M N, arranged subcator, substantially asdescribed.
